This invention relates to a device for pre- -venting clogging andjamming of conveyers -of bottling machinery.

Our new combination includes a safety device or safety gate to be usedon labeling, crowning, and filling machines, and the object of ourinvention is the production of a combination whereby when the conveyerof a bottling machine becomes clogged or jammed, the bottles will not bebroken, as would be the case without employing our invention, but uponthe bottles becoming jammed or clogged, simple and efficient means isprovided for automatically stopping the conveyer.

With these and other objects in View, our invention comprises certainnovel combinations and arrangements of parts as will be fullyillustrated in the oflicial drawings, specifically described in thefollowing specification, and more fully pointed out in the appendedclaim.

' In the drawings:

Figure 1 is a fragmentary view of a bottling machine, showing incombination therewith our improved device for preventing clogging,jamming, and breakmg of the bottles being handled, while Fig. 2 is aview in side elevation of the mechanism depicted in Fig. 1.

Fig. 3 is a sectional view taken on lines 3--3, Fig. 1, looking in thedirection of the arrows.

Fig. 4 is an enlarged, fragmentary, perspectlve view of anotherembodiment of the present invention.

Referring to the drawings by numerals, 1 designates the frame of themachine, and 2 are the sides of the conveyer supported upon the frame 1by means of brackets 3. Between the sides 2 travels the upper run of theconveyer belt 4, and on this belt 4 are fed the bottles shown by dottedlines 5 Fig. 1.

We provide a gate 6 in one of the sides 2, which gate is hinged at 7tothe side of the conveyer, andthe gate constitutesa part of thesidewhen closed, very evenly and satisfactorily holding the bottles uponthe conveyer during. their travel from the turret 8 to the point ofdistribution on the conveyer. l

A vertical, reinforcing metal strip 9 is interposed between ,the hingeof the gate 6, so as t0 satisfactorily strengthen' the gate and at thesame time form an efficient surface to which is attached the hinge ofthe gate 6. A bowed spring 10 has its outer free end bearing against theouter face of gate 6, and the inner end of spring 10 is fastened byscrews 11 to the side of the conveyer, Fig. 2.

An angle bracket 12 is fastened by bolts 13 -l blade 15; the extremeupper end of blade 15,

is preferably provided with a head 16 to prevent accidental displacementof the blade 15 out of the aperture 14 in the bracket 12.- The switch17, of which blade 15 constitutes a part, is fastened to the frame 1 ofthe'conveyer or machine proper, beneath the gate 6, so that when thepressure of the clogged or jammed bottles in the conveyer causes thegate to swing outward, the switch blade 15 will be pivoted outwardly orto an open position (see dotted lines, Fig. 3), whereupon the motordriving the conveyer will be stopped, as the movement of the blade 15 ofthe switch, caused by the opening of the gate, will break the circuit.

Referring to Fig. 4, in this embodiment, the same principle is disclosedwith the addition of a table or platform 18 built on substantially alevel with the floor of the 'conveyer so that when the bottles arepushed the case of belt power being used, the operator upon seeing thegate opened resulting in bottles unonthe table or support 18, canquickly stop the machine before any damage is done.

To allow a. free movement of the blade l5 in the box 1T, the upper edgeof the box is notched at 20 so that the gate can have sufficientmovement to permit the bottles that are jammed to lnove outwardly and atthe same time open the switch for breaking the circuit.

In our combination, the sides of the bottle conveyer constitute anessential part, as well as the construction of the bracket attached tothe gate and the switch position under the bracket. as described.

From years of experience with bottling machinery, we know that thedescribed com bination is an efiicient and valuable improvement in abottling machine, and that the application of the device is simple, yetits utility is comparatively great.

That we claim is:

In a bottling machine, the combination with a conveyer provided .withparallel, sides, said conveyer including a traveling belt, of a gateforming a part of one of the sides of the conveyer, a verticalstrengthening piece secured against one end of said gate, a hingefastened to said strengthening vpiece and to one side of the conveyer, abowed spring pressing at its outer end against the gate and beingfastened at its inner end to the side of the conveyer, an angle bracketsecured to the gate in front ot' said spring, and said bracket providedwith a horizontal portion having an elongated aperture, a switch securedbeneath said gate and bracket and including a box and a blade, said boxbeing notched at its upper end for receiving the blade, said bladeextending through the elongated aperture of the bracket, and said bladehaving a head formed upon its upper end.

In testimony whereof we hereunto aiix our signatures.
